WEIGHING AND FILLING MA CI'ZHQ'E.

Original application filed March 20, 1924, Serial. No. 700,562. Divided and this application filed August Thi invention relates to improvements in Weighing and fill ng machines.

My improvements are especially designed and at the same time quite simple in structure.

Second, to provide an improved filling machine of very large capacity.

Third, to provide an improved 'bagfilh ing machine which requires but little eiiort on the part of the operator.

' Objects pertaining to details and economics of construction and operation of my invention will. definitely appear from the detailed description to follow. V

\I accomplish the objects of my invention by the devices and means described in the following specification. clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing forming a part oi this application, in which:

Fig. I is a front elevation of'a structure embodying the features or my invention, portions of the hopper and base being broken away.

Fig. II is a looking from the right of Fig. I. v

Fig. III is a detail front elevation corresponding to that of Fig.1 with the parts in another position. Fig. IV is a. fragmentary front elevation of the parts shown in Fig. III showing them in another position.

Fig. V is a fragmentary view mainly in vertical section on line 5 of Fig. I;

In the drawing similar reference numerals indicate similar parts in all of-the views. listening to the drawing, I provide a frame consisting of a base land pedestal 2 mounted thereon carrying the hopper 3 and the ejector cylinder 4. Within the ejector cylinder is a feed rotor designated geneiw ally by the numeral 5. This rotor is illuscarrier The inventionv is fragmentary side elevation feed passage. 6,

trated and described in detail in my application for Letters Patent, Serial No. 700,-

567, tiled March 20, 1924 of Which applicacation this is a division. The rotor cylinder has a discharge passage 6. The machine is designed to deliver to valve bags 8 which are slipped uponthe spouts 7, the upper end of one of the bags 8 being indicated by dotted lines in Fig. V. A pair of these spouts 7 is provided the spouts being adjustably mountedat 9 on a 10 which is supported r or oscillating movement so that the spouts are alternately brought into registering relation with the discharge passage 6.

The carrlcr 10 is pivotally, mounted on the scale beam 11, the scale beam being pivoted at 12 and having a Weight 18 at its outer end. The carrier 10 is pivoted on the scale beam at 14 and is provided with a yoke .15 at its upper-end with which the actnating-leverlfi coacts, the lever being pivoted at 17 and rovided with a roller 18 engaging the yo c. with seats 19 at its ends.

The lever 16 is actuated by the spring 20 Whichslidably engages the slotted arm 22 on the upper end of the. lever. parts thus arranged, When-the member 10 is raised the spring is placed under stress storing power for actuating the lever. When the carrier'is lowered as by the tilt- The yoke is provided With the 1 ing of the scale beam under the Weight of the filled bag, the lever is swung by the spring to the opposite end of the yoke, thereby oscillating or swinging the carrier. The carrier is provided with twoports 23 adapted to alternately register with the p the carrier during its oscillating movement constituting a valve for the passage sothat it is a combined valve and spout carrier.

It is intended that the operator shall place a bag upon the spout in inoperative position being filled so that as soon as the discharge passage isuncovered a bag is-in' while a bag is position to receive it. A platform 2 t pivotally and slida'bly mounted ed for supporting the bags, the pivots being slidably supported by the plates 26 having vertical slots 27 therein. The pivots are carried by the platform. hangers 28 which are carried by the scale beam.

at 25 is provid- The platform is supported in its erected I position by the latch 29 on the hanger which is held in engaging Josition with the keeper 30 on the platform by means of the spring 31. On the downward'movement of the platform occasioned by the tilting of the scale beam, this latch comes in contact with the trip 32 releasing the latch and allowing the platform to tilt and discharge the filled bags into the chute The downward movement of the scale beam also releases the spouts so that the spouts tilt substantially simultaneously with the tilting of the platform to discharge the bags.

The spouts are held in their erected position by the keeper arm 34 under which the upwardly projecting arms 85 on the spouts project when the spouts are in filling position; that is, the arms alternately swing under the keeper as the member 10 oscillates. When the carrier moves downwardly the arms 35 pass from under these keepers allowing the spouts to tilt. After the bags are discharged the spout-s are returned to their erected. position by the coiled springs 37. The arm8-i is provided with a thrust bearing 38 under which the member 10 oscillates.

Theplatform is returned to its erected position by the counterweight 39 projecting into an opening 40 in the pedestal, see Figs. I and II where the platform is shown in erected and discharging positions.

My improved filling machine is of very large capacity and the labor in operating the same is minimized.

I have illustrated and described my improvements as l have embodied the same in a device which I have found very practical. l have not attempted to illustrate or describe certain embodiments or adaptations which I contemplate as I believe the disclosure made will enable those skilled in the art to embody or adapt the same as may be desired. v
